The Discussion of Condition-Based Maintenance on Mine Cable

Abstract:

Cable condition-based maintenance is a high pertinence maintenance mode, with a good time effectiveness and economic comparing with planned maintenance. Three steps are needed in the procedure of practicing condition-based maintenance on coal mine, which are choosing state parameters, on-line monitoring, and state diagnosis. Having an advantage and disadvantage analysis on common on-line monitoring methods, the methods are corresponding to different state parameters. Combining with the actual condition of mine, present that the additional low frequent current method is easy to perform, meanwhile, the method is both fit for MVV, MYJV cable and MYP cable. Separately introduce two kinds of on-line diagnosis methods, one is based on the decision tree, and the other is base on fuzzy grey theory. The former adopt minimum entropy to choose testing feature, furthermore generate sub trees, the latter choose weight coefficient which according to the professors experiences to form cable diagnosis model. State diagnosis is the core in cable state maintenance, so how to establish an intact, scientific diagnosis model is the key.
